SOIL MOISTURE MONITORING IN LOAM CONDITIONS

Stevens Water Monitoring Systems’ Hydra Probe soil moisture sensor now comes with a new loam setting feature that covers more of the soil triangle spectrum. Loam is a term used to describe a soil that contains mixtures of sand, silt and clay. The new firmware calibration model is based on the work of Mark Seyfried from the USDA-ARS and Keren Humes from the University of Idaho. The new loam setting is a calibration model now programmed into the Hydra Probe that was determined from a variety of different soils taken from different depths. This new calibration curve will make the Hydra Probe even more accurate over a wider range of soil types.
